Jurjen Luykx

Assistant Professor - medical

Biography

Jurjen Luykx obtained his medical degree at Utrecht University in 2005. He was a visiting scholar and was trained in neurogenetics at the University of California, Los Angeles (UCLA) in 2006/2007. In 2012 he finished his residency in psychiatry and has since held several clinical consultant positions at psychiatric hospitals in Arnhem and the Utrecht area. In March 2013 he obtained his PhD in neuropsychiatric genetics at Utrecht University. Starting February 1st, 2019 he heads the residency program at GGNet Mental Healthy in Apeldoorn, where he also sees outpatients suffering from a range of psychiatric disorders.

Research line

We welcome master students with an interest in psychiatric genetics coming from different backgrounds. A lot of the work we do concerns biostatistics; some of the work also involves wet lab activities.With our lab of postdocs, PhD students, lab technicians, bioinformaticians we focus on the following projects:

• Targeted DNA and RNA sequencing in schizophrenia and bipolar disorder
• Genetic overlap studies: ALS-schizophrenia, OCD-schizophrenia, metabolic traits-schizophrenia, and EEG-epilepsy
• Other genetic studies in psychiatric patients: PTSD-related phenotypes; Pathway analysis studies in schizophrenia; Genetics of clozapine use (www.clozinstudy.com); Genetics of antipsychotic-induced weight gain; Genetics of ECT responsiveness; EEG genomics.
• I am also country coordinator for the Prednisolone trial (placebo-controlled randomized trial studying the effects of prednisolone addition to antipsychotics), EULAST (European randomized controlled trial studying treatment effects of oral vs depot antipsychotics and pharmacogenetics in schizophrenia) and RAPSODI (trial into add-on of raloxifene vs. placebo in the treatment of schizophrenia).
